Next time the vehicle stalls, you need to be checking for spark and fuel. One will be missing. Then you would start your diagnosis.
Is the check engine light on?
No CEL.
Fuel system is as good as new since that thief mechanic went through it completely and replaced a perfectly good fuel pump for no reason.
I could check to see if there is arcing in the wires but since it runs so perfectly when it is running I doubt that the wires or coil are at fault.
Are sure that the fuel system is good as new? just because he replaced the pump doesn’t mean the system as whole is good. even if he went through and checked the system the fact that he replaced a perfectly good fuel pump means one of two things he’s incompetent or just wanted screw your friend over. so just don’t go ruling out the fuel system so fast. at least not until you’ve gotten it checked by a competent and trust worthy technician. there’s a number of things within the system that could be at fault such as the pump relay, fuel pressure regulator, injectors, etc. next time it happens tell your friend to cycle the key a few times and listen for the pump to make sure it is priming the system.
the way you described it im thinking something within in the system whether its in the fuel or ignition system is over heating due to the fact that he can run it for hour and its fine but then suddenly stops working and then doesn’t work again until everything has had a chance to cool down
+1 to what dreamer said. the best way your going to diagnose this problem is when it stalls. your not going to get very far in between stalls because from what i understand from reading your post is that the problem what ever it might be is not present all the time. therefore your only going to be able to diagnose it when its present.
Yes that has the same propensity for ignition switch problems as your Acura. Try ‘jiggling’ the key in the ignition as the engine runs, if it stalls replace the electrical portion of the ignition switch. You don’t need to replace the mechanical portion just the electrical portion, it can be found at the Honda dealer (probably in stock) fairly reasonable.
Just wanted to add that a pinched or restricted gas line can cause similar issues. Usually the gas line is not properly placed back in position when a previously dropped gas tank is being repositioned back into place. The restriction will ultimately cause the gas line to collapse on itself, and cut off gas to the engine.
Good luck and keep us posted.Quoted From BigC:

Good luck and keep us posted.You know it’s funny that Honda has probably the least amount of problems with fuel pumps compared to other makes and they are also probably one of the only manufacturers to put access plates above the tank where the fuel pump is placed so that you don’t have to drop the tank to replace the pump or the sending unit.
Sounds like the same thing that happened with my 99 accord. Same exact symptoms. It would die every couple of days. It would always restart then die again after driving. There was a recall on the ignition switch wiring harness for this year and model. It’s an easy fix. I had the first one done by the dealership a few years back and the second one I did myself. It’s a pain in the butt getting it out, but I think it took a total of 45 minutes to get the old one out and the new one in. If you google it there are step by step instructions along with pictures on the web. I think the cost was around 45 bucks
Good luckI’m surprised no one mentioned the main relay – aren’t the symptoms very similar to what he described?

No. Main relays cause a ‘no start’ normally in hot or cold weather and I have yet to see one that causes the vehicle to shut off while driving. Here’s a great link on Main Relay issues that a viewer sent me.

Great link – Thanks!
A buddy of mine had an older Dodge Intrepid that did the exact same thing several years ago. It ended up being a crank position sensor. Just throwin’ it out there.

Those don’t normally have issue on Hondas and even when they do they often just set a check engine light code, I have yet to see a Honda not start because of a CKP issue. Thanks for the input.
